We revealed last week that the former X Factor hopeful, dropped at bootcamp in 2008, would be appearing on the show this week.
The 21-year-old signer explained how she’s been trying to make it in the industry for the past five years, hoping to finally step out into the spotlight herself after years of baking singing.
Joelle has previously performed alongside the likes of Gabriella Cilmi, Toni Braxton and Rihanna.
Performing a unique take on Adele hit Rolling In The Deep tonight the audience (and us!) certainly seem to love Joelle, and all of the judges are bopping along.
And the buzzers soon followed, with Will.i.am the first to turn around. Danny went next, followed by Sir Tom and finally Jessie.
Danny told her: "Within the first couple of bars I was sold, you did a fantastic job, you made that song your own. I think your control is incredible... I'd give my left arm to work with you."
Jessie J raved: "I'd l love to write a song for you, to hear you sing a song that has so much story and you carried it. As a female to female, I would like you in my team. Our voices together could be insane."
Will.i.am argued: "I know I don't sing like Jessie, yourself or Adele, but I know how to work with good singers. I'd like to work with you as an artist."
Tom added: "I love the way you sing, for me it's coming in my heart."
Left with a tough decision, Joelle said: I'm just so humbled by you guys, thank you so much.
"I honesty don't have a clue who choose, I love all of you... I gotta go with my gut instincts and it's telling me.... will.i.am!"
